Why Does My Skin Get Oily in Northern Taiwan? Oiliness and Solutions

As soon as I returned to the northern region, my T-zone became excessively oily?

I am from the northern part of Taiwan and have had oily skin, acne, and sensitive skin since puberty.
My oiliness was so severe that I had to use several oil-absorbing sheets, and regular tissue couldn't absorb the shine until last September when I started university in Kaohsiung.
I found that the problem was resolved; using the same skincare products (a basic moisturizing serum and lotion for sensitive skin), my skin's oil production returned to normal, with only a slight sheen.
In Kaohsiung, I was also diagnosed with rosacea (which I learned was not just simple sensitivity), but after taking medication for a while, it almost never recurred.
It only flared up again when I returned to school after the winter break, which I suspect is due to the significant difference in weather between the north and south affecting my skin stability.
However, the oiliness issue is really noticeable; when I go home for the weekend, it's no exaggeration that I experience excessive oiliness that very night, and it only returns to normal once I go back to Kaohsiung.
Why is the oiliness affected by location? Is it because the northern region is more humid? I would like to know what methods can help resolve and improve the severe oiliness, as I start to shine with oil less than five minutes after washing my face.
The skincare products don't seem to absorb well, and my face appears oily and dull, in stark contrast to the healthy and bright glow I have in Kaohsiung.
It's very frustrating.

Indeed, the level of oiliness is significantly related to the environment and climate, so cleansing should be adjusted accordingly.

More Info

The issue of oily skin, especially in the context of living in Northern Taiwan, can be attributed to various environmental and physiological factors. Your experience of having oily skin and acne during your teenage years, which improved significantly after moving to Kaohsiung, highlights the impact of climate on skin health.
Firstly, the climate in Northern Taiwan is generally more humid and cooler compared to Kaohsiung, which is warmer and drier. Humidity can increase sebum production as the skin tries to maintain its moisture balance. When the air is humid, the skin may produce more oil to protect itself from moisture loss, leading to an oily appearance. In contrast, the drier climate in Kaohsiung may have reduced your skin's oil production, allowing for a healthier balance and less oiliness.

Sebum, the oil produced by sebaceous glands, serves several important functions. It helps to maintain skin hydration by preventing water loss and provides a barrier against environmental irritants. However, excessive sebum production can lead to clogged pores, resulting in acne and other skin issues. Normal oiliness can vary from person to person, but if your skin feels excessively greasy shortly after cleansing, it may indicate overproduction of sebum.

To address your oily skin concerns, consider the following strategies:
1. Cleansing Routine: Use a gentle, foaming cleanser that can effectively remove excess oil without stripping your skin of its natural moisture. Avoid harsh soaps that can irritate the skin and lead to increased oil production as a compensatory mechanism.

2. Moisturizing: Even oily skin needs hydration. Opt for lightweight, oil-free moisturizers that contain hydrating ingredients like hyaluronic acid or glycerin. These can help maintain moisture without adding excess oil.

3. Exfoliation: Regular exfoliation can help remove dead skin cells that can clog pores and contribute to oiliness. Use chemical exfoliants like salicylic acid or glycolic acid, which can penetrate the pores and help regulate oil production.

4. Diet and Hydration: A balanced diet rich in fruits, vegetables, and whole grains can support skin health. Staying hydrated is also crucial, as it can help regulate oil production.

5. Environmental Adaptation: Since you've noticed a significant difference in your skin condition based on location, consider adjusting your skincare routine based on the climate. In more humid conditions, you may need lighter products, while in drier climates, richer moisturizers may be beneficial.

6. Consult a Dermatologist: Since you have a history of sensitive skin and rosacea, it is advisable to consult a dermatologist. They can provide personalized recommendations and may suggest treatments such as topical retinoids or prescription medications to help manage oiliness and acne.

In summary, the environmental factors in Northern Taiwan, particularly humidity, can significantly influence your skin's oil production. By adjusting your skincare routine and considering the climate's impact, you can better manage your oily skin and achieve a healthier complexion. Remember that skin health is a dynamic process, and what works for you may change with different environmental conditions.
